In plant cells what forms midway between the divided nuclei during cytokinesis

Cell plate

Explanation:

Cell plate is a plate that forms during the cytokinesis of the plants, and helps in separation of chromosomes in two new cells and in new cell wall formation. Vesicles that contain components for the new cell wall and cell membrane) are transported from the Golgi apparatus to the to the plane of cell division. Vesicles fuse within the plate. Direction of the cell plate growth is from the center towards the plasma membrane. This growth depends on phragmoplast, structure that acts as a scaffold. When cytokinesis is complete, cell plate becomes the new cell wall.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
